The motor of new energy vehicles, the rotor of wind turbines, the filter of 5G base stations... These modern industrial "big heart" components all secretly hide a "invisible small motor" - a magnet. As the world's largest producer of magnetic materials, China's magnet industry is undergoing a critical period of transition from traditional manufacturing to high-end technology.

New energy vehicles: the 'wealth highway' of neodymium iron boron magnets

At Tesla's Shanghai Gigafactory, each Model 3 permanent magnet synchronous motor has to consume 1.5 kilograms of neodymium iron boron magnets. This "magnetic giant" material, relying on a magnetic energy product of 400 kilojoules per cubic meter, has "pulled" the motor efficiency to 95%, saving 30% more energy than traditional motors. The global demand for neodymium iron boron in new energy vehicle motors is expected to exceed 50000 tons in 2024, and the market size is expected to exceed 30 billion yuan by 2025. Domestic leader Jinli Permanent Magnet has vertically integrated rare earth resources, and its products cover 70% of the world's new energy vehicle brands, becoming a "favorite" core supplier for companies such as BYD and NIO.

Wind power generation: the 'green transformation' of superconducting magnets

In the wind farm in Siziwang Banner, Inner Mongolia, a 5-megawatt wind turbine generator requires 4 tons of neodymium iron boron magnets. These magnets can maintain a stable wind energy conversion efficiency of 92% at low temperatures of -40 ℃. In 2024, neodymium iron boron motors accounted for 65% of the newly installed wind power capacity in China, driving demand for 120000 tons. What's even more impressive is that the high-temperature superconducting magnet technology developed by Zhongke Magnetic Energy has been applied to 10MW offshore wind turbines, increasing single unit power generation by 40% and reducing costs by 25%.

Technological breakthrough: a leap from the "small stage of materials" to the "big world of systems"

Faced with the shortage of rare earth resources, Beijing Sanjili Company has developed the "nanocrystalline composite neodymium iron boron" technology, which reduces the amount of rare earth used by 30% while maintaining performance. This technology has been applied to high-end headphones from international brands, reducing product weight by 20% and improving sound quality by 15%. In terms of recycling, China has built the world's first neodymium iron boron green recycling production line, which extracts 99.9% of rare earth elements from waste motors through high-temperature vacuum melting technology. The resource recycling rate reaches 95%, and the annual waste processing capacity exceeds 100000 tons.
